Mares Unisex Adults Avanti Quattro + Diving Fins - Durable Efficient Versatile Open-Heel Scuba Fins with Four-Channel Design & Bungee Strap

these fins are great. fly through the water with ease. love the bungee strap. easy to take on and off. even with full dive gear on and on a rocking boat. fins stay where they are supposed to. Have used these on many many dives. dive buddies and groups always say it is very easy to spot me under water because of the bright green color. have even had some friendly aquatic animals follow along. perhaps they like the color too. I wear U.S size 10.5- 11 shoes. I use the large fin and 10 mares 2mm bootie. the XL fin was way too big. the 11 bootie kinda worked but the 10 is a lot better and snug fit. the 11 bootie felt like the water could pull it off.

I've used these fins a couple dozen times now and am impressed. I read a couple reviews on other sites that suggested leg cramps were caused because of these. I haven't found that to be true, thus far.What I love: the bungee strap! In and out of the boat is a cinch with these straps--I'd never want to go back to a buckled strap. Also, these are very lightweight compared to other fins I've used. They have enough room in the foot pocket that they can be worn with boots, but they are also closed enough that they can be worn with just dive socks/booties if that is preferred. I typically dive with Cressi Palma 3mm "boots" (socks, really) and they work great with these fins.Cons: the white color gets marked up quickly from the black rubber accents. Also, don't be tempted to wear these barefoot. Most people don't wear open heel fins barefoot, but I've done it a few times anyway with different fins and was fine. These straps will not allow for that.Addressing the cramp issue--I feel like that is much more a problem with diet, exercise, and technique than it is with a particular fin. The same can be said of any sports related cramp. I've cramped once in all my diving, and I was just coming off leg day at the gym and wasn't hydrated. Don't be afraid of these fins because of a few cramped-leg reviewers...I honestly do not know how these would contribute AT ALL to cramping.

I've been using Mares Avanti Quattros for years and could keep going with my old ones, but I just wanted a new pair as my edges were becoming slightly curled and the stiffness was not so stiff as new... in time all things tend to wear out and hopefully I'll still be diving enough to wear these out, too. They're that good in terms of allowing my best maneuvering and positioning for the sake of doing underwater photography.

Best fins I’ve used so far!! Easy to put on and take off. They feel secure the whole time and provide great mobility in the stronger currents.

These are the best all-around fins that money can buy. They don't have all the bells and whistles but they are tried and true, with a great fit with booties on. They are large so they really propel you through the water.

Idk I haven’t had them long enough to give a full review. But after 17 dives, they are pretty badass. Super comfortable. I wear a size 11.5 and had to put in the strap extender. Can’t even feel them. They have decent power. I’d say if a current wins a battle against these fins you have bigger problems. Very neutral buoyancy. They float but a tiny clip will sink them. My only complaint is they don’t drain water well, at all. So when you’re coming out of the water shore diving you have two buckets with you.

I wear a mens US size 7.5 generally. I went with a size 7 Mares Flex DS 5mm boot and chose the size small fin based on the chart and not going up a size to accommodate the boot. Just fit! Boot slides in and leaves 1inch hang. Foot in the boot, it hits the sides of the cup just to qualify as a snug fit towards ankle while leaving toe wiggle room in the box. If I had moved to a regular it would have been sloppy loose. Fins came with strap extenders to help if strap feels tight. If you have super thick boots or an incredibly wide foot... Go with the regular. Side note.. I def got a pair of returns. They are in great condition so I'm not mad and understand people try them and return them. Consumers.. be kind, put the parts back in the little baggie, don't tear up the warranty and info cards and stop stealing the sticker!

Most comfortable, easy and smooth I have used this fin for over 35 years as a master instructor I have gone thru several sets and I have never seen anything comparable.
